GM62093A

GM62093A GM62093A 12 × 8 CROSSPOINT SWITCH WITH CONTROL MEMORY Description The GM62093A contains a 12 × 8 array of crosspoint together with a 7 to 96 Line decoder and latch circuits. The GM62093A employs LG’s advanced high voltage CMOS process technology. It provides extra low operating current and low power dissipation. Anyone of the 96 switchs can be addressed by selecting the ap-propriate 7 input bits. The selected turned on or off by applying a logical one or zero to the data in and the strobe input at logical one. A reset signal can be used to turn off all the switches together when is switched at logical one. The GM62093A is avail-able in a 40 lead dual in-line plastic and ceramic package.

Seven ADDRESS lines(AX0~AX3, AY0~AY2) are provided to address any one of the 96 switches. After any one of the switches is selected, the DATA pin may be held high to turn the switch on, or low to turn it off. Finally a positive pulse to the STROBE pin initiates the ac-tion determined by the ADDRESS and DATA pins. All 96 switches can be turned off by forcing the RESET pin high. 3 GM62093A Timing Diagram t SW STROBE t SA ADDRESS t SD DATA t DD RESET t DR ANALOG OUTPUT t RW t HD t DA t DS t HA Truth Table AX0 0 1 0 1 0 1 0 1 0 1 0 1 0 ↓ ↓ ↓ ↓ ↓ ↓ ↓ AX1 0 0 1 1 0 0 0 0 1 1 0 0 0 ↓ ↓ ↓ ↓ ↓ ↓ ↓ AX2 0 0 0 0 1 1 0 0 0 0 1 1 0 ↓ ↓ ↓ ↓ ↓ ↓ ↓ Address AX3 0 0 0 0 0 0 1 1 1 1 1 1 0 ↓ ↓ ↓ ↓ ↓ ↓ ↓ AY0 0 0 0 0 0 0 0 0 0 0 0 0 1 ↓ ↓ ↓ ↓ ↓ ↓ ↓ AY1 0 0 0 0 0 0 0 0 0 0 0 0 0 ↓ ↓ ↓ ↓ ↓ ↓ ↓ AY2 0 0 0 0 0 0 0 0 0 0 0 0 0 ↓ ↓ ↓ ↓ ↓ ↓ ↓ Connections X0-Y0 X1-Y0 X2-Y0 X3-Y0 X4-Y0 X5-Y0 X6-Y0 X7-Y0 X8-Y0 X9-Y0 X10-Y0 X11-Y0 X0-Y1 ↓ ↓ ↓ ↓ ↓ ↓ ↓ ↓ ↓ ↓ ↓ ↓ ↓ ↓ 1 0 1 0 1 0 1 0 1 0 1 0 1 0 0 0 0 0 0 0 0 0 0 0 0 0 1 0 1 0 1 0 1 0 1 0 1 0 1 1 0 1 0 1 0 1 0 1 0 1 0 1 1 0 0 1 1 0 0 1 1 0 0 1 1 0 1 1 1 1 0 0 0 0 1 1 1 1 0 0 0 0 0 1 1 1 1 1 1 1 1 X11-Y1 X0-Y2 X11-Y2 X0-Y3 X11-Y3 X0-Y4 X11-Y4 X0-Y5 X11-Y5 X0-Y6 X11-Y6 X0-Y7 X11-Y7 A X =0110, 1110, 0111 and 1111 and not allowed 4 GM62093A Test circuit and Characteristics. l CROSSTALK vs. FREQUENCY Fig.1-Crosstalk l TEST CIRCUIT VIN -90 dB -80 S/W ON S/W ON VOUT -100 50Ω 1KΩ 1KΩ 1KΩ -110 5V 5V 5V 5V -120 -130 VDD = 14 V VIN =2Vp-p 10 10 2 103 f(KHz) l RESULT Fig.2 –analog signal capability(Vin vs. Vout) l TEST CIRCUIT VDD VDD = 12 12 VOUT (V) VDD = 16 16 VIN S/W ON VOUT 8 VDD = 8 VDD = 4 4 VIN = 0 ~ 20 V VCONTROL = 5 V 0 4 8 12 16 (V) VIN 5 GM62093A l RESULT Fig.3-Ron measurement l TEST CIRCUIT VDD R ON Ω 60 S.W ON 10mA 50 40 3.5V 30 +Ä V R ON = ˜V ˜V = I ON 10mA 20 6 8 10 12 14 16 VDD VCONTROL = 5V VDD = 6 ~ 18 V Fig.4-Frequency response. l TEST CIRCUIT dB 0 l BANDWIDTH (-3dB point: ABOUT 45MHz) -2 VIN S/W ON VOUT -4 -6 15KΩ -8 VDD = 14 V VIN=2Vp-p -10 1 10 10 2 f(MHz) 6
